Frankie's driver's license

"Bus the Two of Us" reveals via Frankie's driver's license that she was born on July 25, 1984, making her fifteen years old (five weeks away from her sixteenth birthday) at the time when her license was issued on May 18, 2000, four years before the show premiered.

It is unclear how much older than this she is, except that her license expires in January 2007 and it hasn't expired as of "Bus the Two of Us", making her under 23 years old, since she would turn 23 on July 25, 2007.

In the episode, "Frankie My Dear", Frankie directly says she 22.


Considered as pretty by a few characters, Frankie is a pale-skinned young woman of tall and slim stature, with green eyes (according to her driver’s license) and long, spiky red hair with bangs, usually kept into a high half-ponytail. She also accessorizes her hair with a deep-purple hair clip.

Her usual clothing features a thin black choker around her neck, a large green hoodie-jacket over a cropped, red-and-white ringer tee with minimalistic Powerpuff Girls symbols on the front depicting Bubbles, Blossom and Buttercup, a deep-purple skirt, golden-orange socks and blue-and-white trainer shoes. She also accessorizes with multiple piercings on her ears.


Frankie is very kind, loving, caring, and good-hearted, but she’s also short-tempered, sarcastic and stubborn.

Character description[]

Frankie Foster is based on the show's creator Craig McCracken's wife, Lauren Faust. She is the funny, friendly, hard-working, kind, capable, easy-going, but still short-tempered granddaughter of Madame Foster. According to her driver's license, she was born on July 25, 1984, is 5-08 ft tall, and weighs 127 pounds and has green eyes (proven in "Destination Imagination", when one of her eyes peeks through a window of the Foster's model). However, there is a timeline glitch: In "The Trouble With Scribbles", Mr. Herriman said she had let the Scribbles out in fall 1984, and she appears to be 2-4 years old in the flashback (or, at least where she's old enough to talk).

Frankie has lived at Foster's nearly her entire life, having moved there in her early childhood. It is unclear what happened to her parents, though Frankie mentions during "Who Let the Dogs In?" that they helped her conquer her fear of ghosts when she was a child.

As she grew into her teenage years, Frankie, who had spent her life in the company of imaginary friends, soon took on the role of taking care of pretty much everything at Foster's. She was placed in charge of cooking, cleaning the house, doing the laundry, running fundraisers, driving the house residents around in the multicolored bus, and otherwise taking care of her grandmother's foster friends in every way. She occasionally shows signs of stress as a result of her many duties, though its primary source seems to be Herriman's constant over-enforcing of the house rules and that he forever expects her to work harder, despite her full workload.

She also knows about Mr. Herriman's fear of dogs as shown in "Who Let The Dogs In?" when a couple with a lost, stray dog comes in and Mr. Herriman is sent into a panic, but Frankie saves him by making the couple and their dog leave and stating that Foster's is not an animal shelter. Mr. Herriman is still traumatized and nervous, as he knows "Dogs eat rabbits."

Still, despite all her work, she does manage to maintain a social life and is even allowed to go on the occasional date (assuming Mr. Herriman doesn't keep her working late with more chores). She is also often swayed by Bloo's "get rich quick schemes" and has proven to be an efficient ally in promoting Bloo's agendas when she feels she can get a good profit or outcome out of it.

She is a fan of punk rock, as revealed in "Everyone Knows It's Bendy" and "Imposter's Home for Um... Make 'Em Up Pals." She is also proficient in web-design, creating and maintaining the Foster's webpage, as seen in "World Wide Wabbit".

According to concept art, Frankie was originally intended to be much younger, like a teenager, and much more into punk rock than she already has been shown to be. Many drawings depicted her being always angry. While her looks have changed, she still had the same shirt (depicting a stylized version of The Powerpuff Girls, another cartoon which Craig McCracken created), green zip-up fleece, and ponytail.

Although she is mainly an in-charge, no-nonsense sort of girl, Frankie can be quite stunning, as seen in "Frankie My Dear," where Mac, Bloo, another imaginary friend named Prince Charming, and a pizza delivery boy named Chris, all develop a crush on her, and in "Good Wilt Hunting", where two nerds, Douglas and Adam, consider her to be a vision of beauty. Frankie can be skeptical at times, as seen in "Imposter's Home for Um... Make 'Em Up Pals", where she thinks Goofball John McGee is not an imaginary friend because of his overly-human appearance, which, to be fair, is not a bad thing. She also has an unhealthy addiction to Madame Foster's home-baked cookies, occasionally indulging in a feeding frenzy, first buying $1,200 worth, and then $2,400 (20 and 40 dozen respectively). She may also have a case of road rage, especially seen in "Good Wilt Hunting," where officer Nina Valarosa, Eduardo's creator, hands out tickets for numerous traffic violations. She also won the election for president of the house in "Setting a President," but resigned when she found out the pay was worse than her old job (and partially because Mr. Herriman was devastated not having his old job).

Frankie also gets extremely stressed out in "Cheese A Go-Go". She has to deal with picking up imaginary friends, running errands and a lawsuit between her grandmother and Jackie Khones over a tuna sandwich. She also has problems with Cheese and the others throughout, which becomes worse when Bloo uses an observatory public address system to tell everyone (including her) that Cheese is an outer-space alien and, in substance, invites the creatures from other worlds to pick him up. The stressing out was also a center point on the movie "Destination Imagination", where she escaped to a world to be pampered by a character named World, a face that could move around onto anything.

Frankie's character design appears to be loosely based on that of Lauren Faust, the show's supervising producer (and real-life spouse of series creator Craig McCracken). Oddly enough, Frankie, unlike her grandmother, seems to have not created an imaginary friend of her own, most likely because she grew up surrounded by them. However, she is most likely to have adopted World.

Her favorite TV show is a soap opera called The Loved and the Loveless, which is very popular among the house residents.



Despite the large age difference (at around 14-years), Frankie and Mac are best friends, with the former seeing the latter (who has a secret crush on her) as a younger brother. Mac's the only child that Frankie sees every day to make sure that Bloo (his imaginary friend) hasn't been adopted and is willing to help him vice-versa.

Frankie's usually soft towards Mac because he never gives up on his best friend Bloo, and that he tries to stay out of trouble despite Bloo's antics. Mac is usually one of the only characters that Frankie trusts the most because of his sensible and mature personality and that he's the smartest of the group.


Frankie has a double-edged relationship towards Bloo, because he keeps getting in trouble due to his crazy schemes and his antics and that she easily gets frustrated with him whenever he makes a mess in the house and refuses to clean it himself and have Frankie do his chores for him. Despite Bloo's rebellious and narcissistic personality, Frankie cares enough about him to make sure he doesn't get adopted regarding Mac's promise of seeing him every day.


In FusionFall, she's found standing outside the Foster's gate. She is worried about Coco running off (a reference to the episode "Mondo Coco", when Coco goes through various misadventures and comes in contact with various obstacles when somebody leaves the door to Foster's open. At the end of the episode, Frankie yells, "Who left the door open!? Who knows what would happen to Coco if she got out?!") and Mac going to find her, but she expects them to be at the KND Jungle Outpost. Nearby the house, Mandark, has started the construction of an Imaginasium so he can better study Imaginary Friends. Frankie has gotten into arguments with him about the designs. Eddy secretly has a crush on her, and only mentions it in one of the Imaginary Reinforcements mission parts. She gave her hair clip to the KND and Urban Ranger's scientists for nano development.

  • Frankie has five different outfits: her usual clothes, her formal outfit, her black dress, and her green dress. Two of her outfits were introduced in "Frankie My Dear". In addition, she also has a Blossom (PPG) costume and a choker.
  • Frankie's inspiration to that of Jessica Spencer from the 2002 film The Hot Chick.
  • Frankie's full name is spelt "Francis", as shown on her Driver's License. Interestingly, "Francis" is typically the masculine spelling of the name, while the feminine spelling is usually "Frances".
  • The only episodes where she has non-speaking appearances are "Partying is Such Sweet Soiree" and "Eddie Monster". Coincidentally, they're both season premieres.
  • Frankie's hairstyle bears a striking resemblance to that of Vicky from the Nickelodeon cartoon The Fairly OddParents and Roxinaou Ishi from the Kids WB pilot Go! Go! Moba Boy!. Coincidentally, all three share the same voice actress, Grey DeLisle.
  • Frankie makes a cameo appearance in the OK K.O.! Let's Be Heroes crossover special "Crossover Nexus", as one of the Cartoon Network heroes that was summoned and defeated by Strike.
  • Among the main characters, Frankie is one of the characters that never was arrested and jailed during the series. The others are Goo, Cheese, Terrence and Duchess.
    • If shrinking the cast down to the main eight characters, Frankie is the only one never arrested and jailed.
  • Despite generally being a responsible and hard-working person, Frankie is known to be clumsy and negligent sometimes, making her actions indirectly cause some problems, especially from other characters like Bloo.
    • In the third part of the pilot "House of Bloo's", Frankie left the keys of the cage of the Extremeasaur in the keyhole when she and the gang were returning to the mansion after "rescuing" Duchess, who took advantage of this, used the key to re-open the cage and set free the Extremeasaur as part of her plan to eliminate Bloo.
    • In "World Wide Wabbit", when Mac convinced Frankie to erase a humiliating video of Mr. Herriman, she destroys all the CDs that contained the video, but she forgot to delete the file in her computer, allowing Bloo to upload the video to the internet; furthermore, Frankie, for unknown reasons, didn't have any qualms in that Bloo was using her computer without watching him.
    • In "Bus the Two of Us", Frankie left the keys of the bus inside of the vehicle's ignition when she asked Bloo to close the door of the Bus, giving to Bloo the temptation of take the bus and, despite trying to resist this, he gave in and stole the bus, causing a lot of problems and issues on the road.
    • In "Cheese a Go-Go", Frankie, despite knowing how naughty he is, tells Bloo to keep and watch Eduardo and Cheese in the bus while she and the others were in the courtroom, causing Bloo to take Cheese to an observatory and contact the "aliens" to make them believe that Cheese was one of them; Bloo also leaves Eduardo alone and confused in the streets, causing panic among the public. Furthermore, Frankie was unaware that she parked her bus in a "no parking zone", and the bus was towed as a result, forcing Madame Foster and Mac to go the courtroom again to retrieve the bus, but due to the anger stemming from Madame Foster losing a lawsuit with Jackie Khones, she lashed out to the judge immediately upon seeing him again, causing her and Mac to be arrested.
  • Many fans of the show theorized that Frankie is Madame Foster's imaginary friend (and sometimes, vice versa) due to some of their similarities, such as their clothing design. However, Craig McCracken ultimately disproved this as "both Madame Foster and Frankie are real people, not Imaginary Friends." in a tweet.
    • Also, according to Craig McCracken, Frankie's parents are alive, but as Frankie's father had grown up with Mr. Herriman, when Frankie made her first (and only) imaginary friend, her father made her abandon that friend to never see it again. Frankie started working at Foster's partly because she hopes to eventually be reunited with said imaginary friend.
  • The background image in Frankie's license that is usually a state's official symbol is the logo for Foster's Home for Imaginary Friends.
  • Frankie's shown to be an unattainable love interest in Foster's Home for Imaginary Friends, particularly in “Frankie My Dear”, as 5 different characters were infatuated to her, those being Mac, Bloo, her date Dylan, Prince Charming (another imaginary friend), and Chris the delivery boy.
